由量子分子动力学通常应用的动量相关作用公式出发,引入同位旋自由度后得到了在量子分子动力学中可用于数值计算的同位旋依赖的动量相关作用.并用这个公式较系统地研究了在它的作用下,同位旋分馏比的入射道效应和它们的动力学机理.结果表明所有入射道能量、碰撞参数以及所有的丰中子碰撞系统中子-质子比和质量条件下动量相关作用的同位旋依赖性对同位旋分馏过程产生了重要的同位旋效应,然而它没有明显改变同位旋分馏比对于对称势灵敏的依赖性,即在考虑动量相关作用的同位旋自由度后同位旋分馏比仍是提取同位旋非对称核物质状态方程的灵敏探针.
Based on the momentum-related action formula commonly used in quantum molecular dynamics, the isospin-dependent momentum-related effect that can be used for numerical calculation in quantum molecular dynamics is obtained by introducing the isomorphic degree of freedom. By using this formula, And its action, the isospin-fractionation effect of the entrance channel and their kinetics.The results show that all the energy of the incident channel, the collision parameters and all the neutron-proton collisions of the abundance neutron collision system and the mass-related momentum Isotactic dependence produces an important isospin effect on the isospin fractionation process, however, it does not significantly alter the sensitivity dependence of the isospin fractionation ratio on the symmetry potential, that is, the isospin fractionation ratio after consideration of the momentum-related isomerization degree of freedom It is still a sensitive probe for extracting state equation of isospin asymmetric nuclear matter.
